Re: Aluminum Sleeved Barrels
this is the problem that i thought that might happen when working with high heat calibers, unlike the 22 rimfire. My big concern was the expansion of the aluminum. I dont know how your
barrel was made, but most to date are not epoxied into place, they have an air void between the barrel and alum, the nut pulls the barrel into tension. But no matter i forsee problems with extended shooting like you said. If one was building a hunting rifle where 3 shots would prolly in all likely hood be the most you would ever use at one time this would be fine. The ultralight rifles with the pencil barrels can do this same thing, fire several shots touching, then the third and forth goes astray due to the extreme heating of the thin barrel. More than anything it was a project to see if it could be done sucessfully. ABS carbon barrels are proven to work and would be lighter using carbon over alum. Maybe later this winter i may still make one up just for conversation sake.
Thanks for your input, do you have pics of your rifle?
